any suggestions on mods for the 954. i already have full akro racing system k&n filter power commander with custom map. makin 139/72 right now would like to hit 150. any suggestions on how to get there??
any specific cams in mind that would be good for everyday use? also what about lighter pistons? i have heard of guys changing these out before but cant find a website to buy them from. i also dont want to lose my everyday rider.
ok did some more research and this is the setup im looking at:
port and polish head
webcams racing camshafts
wiseco high comp pistons (13.2)Complete CK kit includes piston, rings, wrist pin, circlips, gaskets and sleeve
Performance profile to increase overall performance. Cam has a reduced base circle. Use F4 factory shims for adjustment. Requires High Compression Piston, and Exhaust System. Price Per Set (2).
Cam Gear, Adjustable
is there anything else i need besides good tuning? what kind of gains would i be looking at?
What is wrong with the K&N filters? This is the 2nd time in 2 days I have heard about this. (Other guy was talking about getting dirt in carbs with them) Seems like a sure bet that the higher flow would give an increase in performance.Start by replacing the K&N with an OEM filter.
Then cams would be a good bet.
First, you would need to determine that the K&N does actually have more flow.What is wrong with the K&N filters? This is the 2nd time in 2 days I have heard about this.

And then you'd need to determine if that particular K&N filter is the same as it was over six years ago when those tests were done. Also, those tests were done with 108 octane race fuel, PAIR system removed, and the stock ECU handling the air/fuel mixture; no PCIII was present (which seems odd since many/most people would add a PCIII and have a custom map done if they ran a full Hindle exhaust or bolt-on, high octane fuel, and a K&N filter). Lastly, the DJ 250 is a full eddy current (load) dyno. Most people cannot look at those results and make an apples-to-apples comparison to our own bikes for many reasons.
I'm making an appointment to have my 954 tuned next month. We have a local shop with a brand new 224xLC and a tech that is trained/certified. Should be fun to watch the process and see what comes of it in terms of performance feel and any change in the linearity of the powerband.
I would love to know what gains you get after changing just the cams. if its significant, then i will do the same.
